Flat earthers claim the existence of a "Shadow Object" to explain eclipses. I would like to understand some details of this part of flat earth theory. Please answer any or all of the following:
1. Is the Shadow Object (SO) disk-shaped, nominally spherical, or some other shape?
2. What are the SO's approximate dimensions?
3. What is the SO made of?
4. Why can't we see the SO directly, rather than inferring its existence when we see an eclipse?
5. What natural force is responsible for the SO's movement in the sky?
6. Where is the SO when it is not causing eclipses? For example, where is it today, Dec. 10, 2014?
7. When it is not eclipsing the Sun or Moon, shouldn't it be blocking some other part of the sky which we could verify?
8. How far from Earth is the SO?
9. Keeping in mind that the existence of eclipses does not prove the SO exists (since round earth theory can also explain eclipses without conjuring a shadow object), what evidence do you have that the SO exists?
